Coating knowledge: analysis of four methods to improve the powder loading rate of powder coating

Core tips: 1 Control the particle size distribution, the narrower the better: reasonably control the particle size of the powder (it is difficult), in our actual production only adjust the speed of the main and secondary grinding of ACM The powder size of 40-50um is suitable, the narrower the distribution is, the better 2 Improve the resin content: increase the resin content, reduce the filler content, select the resin with good electrical performance, epoxy is better for powder application, some manufacturers can't use polyester powder, some manufacturers can't use polyester powder, some manufacturers can't use polyester powder (separately grind epoxy and polyester into powder spray plate), the spray level of friction spray gun is obviously better than that of electrostatic gun, and the friction gun can spray thick coating, and the coating has no disadvantages of high-pressure gun as Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Coating home news: 1 Control the particle size distribution of the powder, the narrower the better: reasonably control the particle size of the powder (it is difficult) In our actual production, only adjust the speed of the main and secondary grinding of ACM The powder size of 40-50um is suitable, the narrower the distribution is, the better 2 Improve the resin content: increase the resin content, reduce the filler content, select the resin with good electrical performance, epoxy is better for powder application, some manufacturers can't use polyester powder, some manufacturers can't use polyester powder, some manufacturers can't use polyester powder (separately grind epoxy and polyester into powder spray plate), the spray level of friction spray gun is obviously better than that of electrostatic gun, and the friction gun can spray thick coating, and the coating has no disadvantages of high-pressure gun Such as big orange peel 3 Reasonable selection of fillers: fineness and dispersion of fillers are closely related to powder loading The precipitated powder is higher than the general superfine heavy barium, and the barium sulfate is better than the calcium carbonate 4 Add electric assistant: add electric assistant in the formula (mechanism: it can make powder particles carry more electric charge There is a strong electric field in the area from the high-voltage electrostatic spray gun to the workpiece, and the air is ionized to produce hundreds of millions of ions When the powder particles of the electrostatics pass through this area, they are polarized, which can catch more negative ions and carry more charges Due to the weak power line of Faraday effect, the powder particles with more charges can reach the surface of the workpiece by their own force, so as to improve the powder loading of these parts Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
